Dynamic tuning for a signal recycled interferometer. — •Dmitry Simakov — Institut für Gravitationsphysik, Leibniz Universität Hannover and

In this work we study a particular method of detection of the chirp signal, the so-called dynamic tuning. The exact simulation of the detector response for the arbitrary signal recycling tuning variation and input signal is performed. Using the response, we calculate the shot noise and prove that it stays white for non-stationary regimes of interferometer operation. This allows us to compute the signal-to-noise ratio of the detection with dynamic tuning. The problem of signal deconvolution is also solved.
